Adding checkbox to Gridview is as simple as adding TemplateField of any control.
将复选框添加到 Gridview 就像添加任何控件的 TemplateField 一样简单。

There should be other columns binding data to the grid. Also, check visible property of checkbox.
应该有其他列将数据绑定到网格。另外，检查复选框的可见属性。

I always just add a column to the DataTable that I am binding to.
我总是只在我绑定到的 DataTable 中添加一列。
dt.Columns.Add(new DataColumn("Include", typeof(Boolean)));
Or in my SQL I will have:
或者在我的 SQL 中，我将有：
declare @include bit
set @include = 0
select
@include Include,

I did work it out in the end, thanks to ExpertSoul for the headsup on the tutorial. This was all I needed in the markup and it worked great:
最后我确实解决了这个问题，感谢 ExpertSoul 对教程的提示。这就是我在标记中所需要的一切，而且效果很好：
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="PublicationSelector" runat="server" />
</ItemTemplate>
</asp:TemplateField>
The other thing that the tutorial had which was great was an onclick event so that you could pick up the id # when the submit button was clicked, which was the next bit...
本教程的另一件很棒的事情是 onclick 事件，这样您就可以在单击提交按钮时获取 id #，这是下一点......
Great stuff.
好东西。
